The 2004 Honda Accord offered two engine choices in North America: a 2.4‑liter inline‑4 and a larger 3.0‑liter V6, with trims and configurations determining which engine you received.
Engine options by powertrain
Honda’s lineup for the 2004 Accord centered on mass-market efficiency with the four‑cylinder as the standard option and a V6 as a higher‑end upgrade. The following sections break down each engine, its typical specs, and where it appeared in the lineup.
2.4-liter inline-4 (i-VTEC)
Overview of the 2.4L engine used in most Accords of the year, including displacement, power output, and common transmissions.
- Engine family and displacement: 2.4 L inline-4 (K-series family, commonly K24A4 in the U.S. market)
- Horsepower: about 160 hp (varies slightly by model year and transmission)
- Torque: around 160 lb-ft
- Typical transmissions: 5-speed manual or 4-speed automatic (later updates introduced additional gears in some trims)
The four‑cylinder was the standard choice for most LX/LX-S and EX trims, balancing performance with fuel economy.
3.0-liter V6
Overview of the larger engine offered in the 2004 Accord, including displacement, typical power output, and common transmissions.
- Engine family and displacement: 3.0 L V6 (commonly J30A family in the U.S. market)
- Horsepower: around 240 hp
- Torque: roughly 212 lb-ft

The V6 was reserved for higher trims such as EX-V6, providing notably stronger acceleration alongside higher equipment levels, but at the cost of lower fuel economy.
Market and trim notes
Not every trim used every engine, and regional variations could apply. In the United States, the 2.4 L four-cylinder powered the majority of the lineup, while the 3.0 L V6 was the engine of choice for the more premium EX and EX‑V6 models. The availability of the V6 was a selling point for buyers seeking more power and smoother highway performance.
Summary
For the 2004 Honda Accord, buyers could choose between a 2.4-liter inline-4 engine or a 3.0-liter V6, with the former serving as the standard setup and the latter offering higher performance on the top trims. This pairing matched Honda’s emphasis on reliability, efficiency, and a straightforward upgrade path for customers seeking more power.
